Construction boards with foil-containing facers
A construction board comprising a foam body said foam body having first and second planar sides. The construction board further comprising a multi-layered facer affixed to said first or second planar side of said foam body. The multi-layered facer including a first foil layer, a first paper layer, a glass fabric layer, a second paper layer, and a second foil layer.
1. A construction board comprising:
(a) a foam body, said foam body having first and second planar sides; and
(b) a multi-layered facer affixed to said first or second planar side of said foam body, said multi-layered facer including a first foil layer, a first paper layer, a glass fabric layer, a second paper layer and a second foil layer.
2. The construction board of claim 1 , wherein the second foil layer is adjacent the first or second planar side of the foam body.
3. The construction board of claim 1 , wherein the glass fabric layer is sandwiched between the first paper layer and the second paper layer.
4. The construction board of claim 1 , wherein the foam body is selected from the group consisting of polyisocyanurate, polyurethane materials, and mixtures thereof.
5. A construction board comprising:
(a) a foam body, said foam body having first and second planar sides; and
(b) a multi-layered facer affixed to said first or second planar side, said multi-layered facer including a first foil layer, a first glass fabric layer, a paper layer, a second glass fabric layer, and a second foil layer.
6. The construction board of claim 5 , wherein the second foil layer is adjacent the first or second planar side of the foam body.
7. The construction board of claim 5 , wherein the paper layer is sandwiched between the first glass fabric layer and the second glass fabric layer.
8. The construction board of claim 5 , wherein the foam body is selected from the group consisting of polyisocyanurate, polyurethane materials, and mixtures thereof.
